Well,I've never had a preg. rat before,but congrats on saving her!
Well,anyways how well can she walk? Do you have shavings as bedding?
If so,I'd suggest switching it to a towel,or a soft blanket. I don't think she'll need another rat
with her,in fact it may be good for her to be by herself.
Maybe someone else can be of more help. Good luck!

Hey everyone here are some pics...

Here is the little boy


and here is the female and her cage...what you think...preggy??

Very cute little lady! Her marking is in the 'high white' range, so when bubs are born, be very watchful for abnormally distended or lumpy baby bellies, as megacolon is a possibility. She does not need a friend right now, but you should keep a female baby or two as a companion for her when the time comes.

The little boy is also very cute. A proper quarantine is a minimum of three weeks AFTER any symptoms of illness have resolved, and should be done in a separate airspace from any other rats. Also, his eyes seem to be pink, not red- so rather than a beige, you are the proud owner of a Champagne or Amber rat, depending upon whether he is Agouti or Self based! He does not look ticked to me, so I'd say he is a Champagne.

Did you see the father of the babies at all?

It is hard to say for sure, but many rats do not show much until they are about ready to deliver. My guess is 3-5 days out at the most. It is time to start supplementing her diet with high protein foods to help with milk production. A scrambled egg with a little olive oil is wonderful- feed about 1 1/2 tablespoons per day of scrambled egg. Chocolate soymilk can be offered to lap from a dish, and is a favorite treat. Fresh kale helps keep the Vitamin K up, which assists in blood clotting- important to stop the bleeding on time after delivery- but not too much, as it contains an acid that interferes with absorbing calcium. Some canned oysters or a little cooked beef liver will provide B-vitamins.

Babies will be able to easily escape that cage when they are born and start to be mobile. I would start looking for a nursery cage with smaller bar spacing now, although it will probably be 3 weeks until you really need it.

She looks far less pregnant in the second set of pics. Nipples do show when not pregnant, but they are not as prominent by far. Give it some time- if in 21 days you do not have babies, time to get her (and quarantine properly of course) a female friend!

If she was in with males for more than a couple of hours, you can be just about certain she is pregnant. Maybe you will luck out and she is not.

Probably pregnant then!

Congrats on your new ratties!!

As previously mentioned you will need to give your girl good healthy nutritious food and extra protein.
I would strongly suggest good quality lab blocks such as Harlan, baby cereal (such as Nestle mixed cereals with fruit, baby cereal), the baby cereal can be mixed up with water, soy milk or soy baby formula, a bit of cooked egg occasionally, vegs such as peas, and fruit .

In the future, when babies are old enough to wean, they will start eating the baby cereal, etc. with their mom.

today she weighs 10.1 oz...so .6 oz in one day??... I am giving her baby cereal, little egg, fruits, veggies, and lab block. She is just a sweety....I have a question though. Her bottom is slightly protruded. Like swollen a little is that bad??? ...

Sure...here is a few!!

I have another question.... There is a beige female rattie that is 4-5 mo old near where I love that needs to be rehomed. I have doubled in my original number in 2 days...but...

She is free to a good home, should I adopt her....

Or wait??

Oh and while I am asking questions- I feed my ratties oatmeal, uncooked pasta, dried bananas, dried pumpkin seeds, Mazuri lab block, Lettuce, carrots, cabbage, mustard greens, apples, and then my maybe preg female all of that and baby cereal... Is that a decent diet???

I have done ALOT of research, and read books, but I like to be well informed....

The swelling looks like she is pregnant to me- a pregnant girl's vulva will swell a bit.

Hold off on adopting another rat. You do not want to do QT on ANOTHER rat while you are waiting for babies, and if she transmitted anything to the momma, babies could be born very sick.

The diet sounds good, but I would replace the lettuce with Bok Choy- lettuce has very little nutrition and is mostly water, while Bok Choy provides some excellent nutrients. Most King Soopers carry it. It is also sometimes called Chinese Cabbage. Also, do add some extra protein to the expecting mommy's diet.
